Computed Tomography Perfusion (CTP) is an imaging modality that generates parametric maps of cerebral hemodynamics which are useful in the assessment of suspected acute ischemic stoke. However, the technology underlying CTP is complex and serious controversy surrounds the safety of CTP tests and the reproducibility and validity of CTP results. This report briefly outlines the history of CTP, its current clinical applications for stroke management, the main controversies surrounding CTP, and future directions for this technology.
